C#.NET — Predict output with general exception handling and out-of-range index. Input provided: "6". What is printed?
-
AException occurred
-
BRemaining program
-
CException occurred Remaining program
-
DRemaining program Exception occurred
-
EThe value 66 is assigned to a[6].
Answer
Correct Answer: Exception occurred Remaining program
Explanation
Introduction / Context:This program converts input to an index and assigns val = 66 to a[index] in a 5-element array. It uses a single catch(Exception) block. We input "6" to trigger an out-of-range access.
Given Data / Assumptions:
- Array: int[] a = new int[5]; valid indices 0..4.
- Input: "6" → index = 6.
- Assignment: a[6] = 66; causes IndexOutOfRangeException.
- catch(Exception e) prints "Exception occurred " then execution continues to print "Remaining program ".
Concept / Approach:Any exception thrown within the try block is caught by the general catch(Exception). After handling, the program continues unless rethrow or exit is used.
Step-by-Step Solution:
index = 6 → a[6] access throws IndexOutOfRangeException. catch(Exception) executes → prints "Exception occurred ". Next, the final Console.Write prints "Remaining program ". Combined output: "Exception occurred Remaining program".Verification / Alternative check:If index were 2, no exception would occur and output would be only "Remaining program ".
Why Other Options Are Wrong:
- A/B: Incomplete; the program prints both messages.
- D: Order is reversed; catch prints first.
- E: Index 6 is invalid, so no assignment occurs.
Common Pitfalls:Assuming execution halts after an exception when it is actually caught and handled.
Final Answer:Exception occurred Remaining program
